i'm not sure if you are still interested in a solution to your problem, since it's been a long time since your post. anyway, i think it's this thing causing the problem:
"(colourB=0, r=radius0.75, fx(t)),fy(t) with filledcurves linestyle 2,"

i rewrote your code to the following and it works:

plot \
for [i=0:rowf-rowi] '+' using (xpos):(ypos(i)) with points pointtype 5 pointsize 4 linecolor i+1 , \
for [i=0:rowf-rowi] filename using (xpos):(ypos(i)):(sprintf('%s(%s)', stringcolumn(1), stringcolumn(2))) every ::i+rowi::i+rowi with labels left offset 3,0 , \
filename using (centerX):(centerY):(radius1.00):(pos):(pos=pos+angleA($4)):(colourA=colourA+1) with circle linecolor var, \
filename using (centerX):(centerY):(radius0.90):(pos):(pos=pos+angleB($3)):(colourB=colourB+1) with circle linecolor var, \
filename using (centerX):(centerY):(radius0.80):(pos):(pos=pos+angleC($2)):(colourC=colourC+1) with circle linecolor var, \
(r=radius0.90, fx1(t)),fy1(t) with l linestyle 2, \
(r=radius0.80, fx2(t)),fy2(t) with l linestyle 2, \
(r=radius0.70, fx3(t)),fy3(t) with filledcurves linestyle 2

Iteration inside a plot command is not possible for parametric plots.
In most cases you can use instead a

For example instead of
set parametric; plot sin(x), cos(x)
Usr
plot '+' using (sin($1)):(cos($1))
